Abstract. Platyptilia galicicaensis sp. n. (Pterophoridae) is described. The species is found in the Republic of Macedonia, Ohrid, Galičica National Park. All specimens were collected around Helichrysum zivojini Čern- javski & Soska, 1940 or H. stoechas (L.) Moench, 1794 (Asteraceae); one or both of these plants is probably the host plant of the new species. Introduction At the end of June 2014 we made an entomological expedition to Galičica National Park, Republic of Macedonia, mainly to investigate the microlepidoptera. In the first days of field work we -ob served a Platyptilia species (Pterophoridae) in large numbers around plants of Helichrysum Mill. (Asteraceae). As larvae of another species of Platyptilia, P. tesseradactyla (L., 1761), have also been recorded from Helichrysum (Hofmann 1896; Hannemann 1977) although they feed on Antennaria dioica (L.) (also Asteraceae) (Gartner 1862; Hofmann 1896; Huggins 1939; Beirne 1954; Gozmány 1962; Hannemann 1977; Buzsko 1986) in Scandinavian and Baltic countries, including Sweden, the type locality of P. tesseradactyla (Gielis 2003), and Finland, where the first author has rearedP. tesseradactyla from Antennaria dioica, we wondered whether the specimens we observed belonged to this species. However, the Macedonian specimens externally resembled P. gonodactyla (Denis & Schiffermüller, 1775) or P. calodactyla (Denis & Schiffermüller, 1775) rather than P. tesseradactyla. As we were unable to find the known host plants of P. gonodactyla (Tussilago L., Asteraceae) and P. calodactyla (Solidago L., Asteraceae) in the locality where the unidentified Platyptilia species occurred, we decided to collect some specimens in order to clarify the species’ status. The genus Platyptilia Hübner, 1825 contains seven known species in Europe: P. tesseradactyla, P. farfarellus Zeller, 1867, P. nemoralis Zeller, 1841, P. gonodactyla, P. calodactyla, P. iberica Re- bel, 1935 and P. isodactylus (Zeller, 1852). Here a new species, P. galicicaensis sp. n., is described. The new species is closest in appearance to P. gonodactyla and P. calodactyla. Both of these spe- cies have several junior synonyms. These were investigated and type specimens were examined by Arenberger (1988); the neotypes are in the Natural History Museum, Vienna (NHMW). In addition to the seven species that occur in Europe, the type specimens of P. chondrodactyla Caradja, 1920 and P. kozanica Fazekas, 2003 were also examined. The genus Platyptilia is distributed in the Holarctic, Neotropical, Afrotropical and Indo-Australi- an Regions. Larvae of Platyptilia are Asteraceae feeders (Hofmann 1896; Barnes and Lindsey 1921; ©Societas Europaea Lepidopterologica; download unter http://www.soceurlep.eu/ und www.zobodat.at 110 JUNNILAINEN & KAITILA: A new species of Platyptilia Hübner, 1825... Schwarz 1953; Gielis 1996). The new species exhibits typical characters of Platyptilia as given in the diagnosis of the genus (Gielis 1996) such as the well-developed costal triangular spot on the forewing, forewing vein R1 present, and the third lobe of the hindwing with a centrally placed scale- tooth. The new species was recorded for the first time at the end of June 2014 and again at about the same time in 2015 in Galičica National Park, near the town of Ohrid, Republic of Macedonia. Specimens were netted around Helichrysum plants at 1450 m a.s.l. in the evening just before sunset. Material and methods The species examined for comparative purposes are Platyptilia chondrodactyla: 1 ♂, Lectotype, 1 ♀, Allotype, both in coll. “Courtesy, the “Grigore Antipa” National Museum of Natural History”, Bucharest, Romania; Platyptilia kozanica: 1♀, Holotype; Platyptilia gonodactyla: 19♂, 10♀, in coll. J. Junnilainen; Platyptilia calodactyla: 24♂, 15♀, in coll. J. Junnilainen; Platyptilia tessera- dactyla: 19♂, 11♀, in coll. J. Junnilainen; Platyptilia farfarellus 2♂, in coll. J. Junnilainen; Platyp- tilia nemoralis 1♂, 1♀, in coll. J. Junnilainen; Platyptilia isodactyla 2♂, 2♀, in coll. J. Junnilainen. All specimens of P. galicicaensis sp. n. were captured with nets late in the evening just before darkness when specimens were active around Helichrysum vegetation. Specimens were stored alive in glass vials and later killed in a freezer and then immediately spread. Later, dry specimens were labelled with the exact collecting data. Then the genitalia were dissected and first preserved in glycerol. After determination and comparative work under an Olympus VMZ 20–80X micro- scope, the genitalia were mounted on glass slides with euparal following the procedure of Robin- son (1976). Later, dry genitalia slides were photographed with a Leica DM1000 microscope and an integrated Leica DF295 digital camera. Original images were cleaned and edited with Adobe Photoshop v. 11.0. The camera system used for images of the adult was a Nikon D800 with a Micro Nikkor 105 mm 1:2.8 D objective and three flash heads. The camera was moved between shots with a Cognisys Stackshot focussing rail. Zerene Stacker v. 1.04 and Adobe Lightroom 6.6 were used for processing the photos; 36 shots were combined in each photo stack. For the DNA analyses, one leg was removed from a dried specimen and moved to a lysis plate with 100% ethanol. A sample identification number MM24208 was given to the specimen. The sample was sent in a lysis plate to the Canadian Centre for DNA barcoding, Ontario, Canada, through the Finnish Barcode of Life campaign. DNA extraction, amplification, and sequencing of the barcode region of the mitochondrial cytochrome oxidase I (COI) gene (658 base pairs) were carried out successfully following protocols by deWaard et al. (2008). The specimen’s taxonomic and collection data, voucher image, COI sequence and GenBank accession number are available in the BOLD database (http://www.barcodinglife.org/) through the public dataset DS-PLATYPEU.
